Figure et is in elevation of theeii' controlling vineens errnnged in operative relation with respect to the. jet elenient.

ence character The jet' elenient il; is 'cup shaped in cross section and comprises e eirculer disc 5, having formed integral thereivitjh un outwnrdly extending coller (i having interior .threads for engagement With the threiid on the nipple l. The inner-fece of the coller 6 is noty threaded entirely throughout endhwhen the jet elernent 4 is mounted position it. proieots e substantial distance frein the inner end edge of the nipple l. n

The plete 5 has its inner, or rather thetface with which the coller 6. is rorined integral, provided with en annular ridgeV 7 \v ich projects toward the inner end of the nipple l. The platte 5. is formed with en inner', `:in interinedigite and en outer circuler row of openings and which are indicated at 8, 9 and y y The openings 9 extend through the plete 5 and ridge 7. The openings gire giri-tinged in proximity to the coller The openings are spaced equidistsnt from the openings 8 and '10.

Arranged eritriorly of the outer end of the nipple 1is n housing 11, which forins a gas receiving ehuinher 12. The housing 1l is providedcentrnlly of its loot-toni with a .vertically disposed leg 13 Which communicetes with :nid is'connected to a, ges supply ppeyleifa The, housing l1 is 'furthermore provided with a pair of oppositely entending, al Y ing later-elly disposed legs 14, 15..

rlhe lee; le communicates with and is c011- lnected to the threads 2 of .the nipple 1 it the outer end of the latter. The outer end oit the leg has formed integral therewith a head-piece 16, which closes the outer end of the said leg 15, and the inner face of the head piece 16 is formed with a protuberance 17 centrally thereof. The head piece 16 1s of polygonal contour and of a thickness greater than the thickness of the body of the housing 11. The head piece 16, centrally thereof is formed with a pocket or socket 18 and communicating with the inner end thereof is an opening 19 arranged centrally of the protuberance 17.

The said element 4 is controlled through the medium ot' a throttle mechanism and which comprises a lengthwise shiftable bar 20 which nextends through the socket 18, opening 19, chamber 12 and into the nipple 1. A packing means 21 is mounted in the socket 18 tor the rod 20. The outer end of the rod 20 is provided with a hand wheel 22 to facilitate the operation thereof. The inner portion of the rod 20 is provided with an adjustable stop collar 23, which is detachably secured to the rod 20, through the medium of the set screw 24. The inner end of the rod 2O has secured thereto a disc valve 25 for closing the circular row of openings 8. Slidably mounted on the rod 20 between the collar 23 and the disc valve 25 is a spring controlled collar 26 provided with a plurality of radially disposed and downwardly inclined arms 27 which terminate in the rear end of a ring valve 28 which is employed for closing the openings 10. Mounted on the rod 20 and interposed between the collars 23 and 26 is a coiled spring 29 :tor controlling the valve 28. The function of the spring 29 is to normally maintain the ring valve 28 projected and said valve 28 surrounds t-he disc valve 25. The length of the body of the ring valve 28, in cross section, is greater than the thickness of the disc valve 25.

Slidably mounted on the nipple 1 is a controlling element for the air supply to the mixing chamber and said air supply controlling element consists of a conoidal shaped body portion 30 having its smaller end terminating in an annular collar 31, which is slidably mounted on the nipple 1 between the rear end of the jet element 4 and the point of connection 32 between the leg 14 and the outer end of the nipple 1. The body portion 30 in proximity to the collar 31 is formed throughout with a row of spaced air inlet openings 33.

The air supply controlling element is adjusted simultaneously with the controlling of the jet element by the throttle mechanism and for such purpose the body portion 30 at its enlarged end has projecting therefrom a pair of diametrically opposed arms 34, 35, and each of which has an angle shaped inner end 36 which is positioned against the inner face of the body portion 30 and is secured therewith by the holdfast device 37. The arms 34 and 35 are secured at their outer ends, by the holdfast devices 38, to the end of a. bow-shaped member 39 formed centrally with an enlarged portion 40 having an aperture 41 through which extends the rod 20. A set screw 42 is carried by the enlarged portion 40 and which acts as a means for tixedly securing the member 39 to the rod 20, so that when the rod is moved inwardly the air supply controlling element will be carried therewith and said element will be moved outwardly when the rod 2O is withdrawn.

The throttle mechanism, which controls the jet element, as well as the air supply con* trolling element, has three positions represented at A and C in dotted lines and at B in full line Figure 2. Secured to the rod 2O in proximity to the wheel 22, is a collar 43, provided at one end with a laterally extending annular flange 44. The collar 43 and flange 44 associate with a ratchet lever 45 to provide for the three positions, referred to, of the throttle mechanism. The lever 45 includes a bifurcated arm 46 for receiving the flange 44 to hold the throttle mechanism in position B. Position A is attained by the abutting of the flange 44 against the outer side edge of the arm 46.. Position C is obtained by the abutting of the flange 44 againstl the inner side edge of the arm 46. The lever 45 is furthermore provided with a handle piece 47, and the inner end of said lever 45 is pivotally connected as at 48, to a lug 49, carried by the body portion 11 ol thc housing.

A mixing chamber which is indicated at 50, is formed by a substantially elongated shell 51, of the desired diameter and length, and said shell 51 has a converging inner terminal portion 52 and a flaring outer portion 53. The shell 51 is arranged conccntrically with respect to the nipple 1 and the jet element 4 is positioned at a point between the vertical median of the shell 51 and the outer end thereof. The nipple 1 is ot' inaterially less diameter than the diameter ot the shell 51.

An air conducting or supply passage 54 surrounds the shell 51, and said passage 1 provided by an elongated shell 55, in connection with the shell 51. The shell 55 is ot greater diameter than the shell 51 as well as of a length to project inwardly with respect to a converging end 52 of the shell 51. The shell 5 has a converging inner end The. shells 51 and 55 are maintained in spaced relation by spider elements 56 which are interposed between the said shells and said spider elements or members are spaced from each other. The point of combustion is indicated at 57. The shell 55 is mounted in and er;- tends through an opening 58 formed in a portion of a. heater or stove or other device with which the burner is used.

rIfhe construction as referred to provides for adjustment relative to air and gas in one operation and such adjustment will be an accurate one. The construction provides lwhereby the velocity oit the gas is not decr ased when the volume thereof entering the minin chamber is reduced, which is brought about by the controlling of the jet element with the medium of the throttle mechanism and the ustment of the et element is had by increasing and decreasing the numberoii active orilices or openings in the plate 5, rather than decreasing the velocity of the gas, as is done in the usual type ot' burner.

By setting up the jet element with a large number of small openings, instead of one opening, it is possible to obtain greater velocity of the gas at a. lower pressure, which insures better mixture of air and gas before the same reach the point ot combustion. The construction or rather shape oli the shell 5l prevents air and gas from channelling or reaching the point ot combustion Without being properly mixed. 'lhe shell 55 Which `provides a jacket for the shell 5i servesa double purpose, one o' which is to protect the shell. 5l and the other ot which is t0 pr vide additional air When the same is desired, which decreases the flow ot the mixture and shortens the flame.

lt is thought that the many advantages of a natural gas burner, in accordance With this invention, can be readily understood, and although the preferred embodiment ot' the invention is as illustrated and described, yet it is to be understood that changes, variations and modilications can be had with respect to the details orn construction which fall Within the scope of the invention as claimed.
